Human health and the future.

Number of people now living within the reach
of malaria-transmitting mosquitoes (potential
transmission zone), worldwide                            2.5 billion

Number of people who will live in the
transmission zone by the latter half of the
21st century, after projected expansion of
the transmission zone by global warming                  4.8 billion

Average number of heat-related deaths in
Atlanta each summer                                               78

Average number projected by 2050, assuming no
change in the city's population size or age
profile, but with projected global warming                       293

Predicted decline in production of cereal
grains (rice, corn, wheat, etc.) as a
result of climate change (climate effects
only) by 2060,

in the developed countries                             -23.9 percent
in the developing countries                            -16.3 percent

Additional decline in grain production from
physiological effects of C[O.sub.2],

in developed countries                                  -3.6 percent
in the developing countries                            -10.9 percent

Number of people at risk of hunger in 2060,
without global warming                                   640 million

Number at risk with projected warming             680 to 940 million

Life expectancy in the most developed
countries in 2000                                                 79

Life expectancy in the least developed
countries in 2000                                                 42

Share of worldwide AIDS/HIV cases that are in
developing countries                                      90 percent

Share of AIDS stories with non-U.S. settings
in the U.S. media                                          4 percent
